With UBCD 5.2.1 only the CPU tests, including CPUstress Menu, Lose all keyboard input after selecting the test. The tests continue to run regardless of key entry, Ctrl-Alt-Del has no affect. My MS-7549 has PS2 inputs, so I plugged in an old PS2 keyboard and erything worked just fine.UBCD 5.1.1 may have had this problem but none of the CPU tests would load, they all failed with "Unable to open RTC0".UBCD 5.0.3 the USB keyboard worked just fine.

UBCD 5.1.1 version of the CPUstress suffers from this bug so you can't even boot from there.

By the way, I am trying to find out whether I need to put some kernel modules to the CPUstress image, and I need some help. If anyone can demonstrate that -- given the same linux kernel and the same USB keyboard -- the keyboard works in Parted Magic but not in CPUstress, then I'm sure the fault is mine.

Hello Older, bob3248 and those who have a USB keyboard,I have prepared a image for you to test if the bug still exists or not.If you like debugging and don't mind formatting a USB stick, you can download this and test:http://dl.dropbox.com/u/70170658/ubcd/c ... 2.2beta.7zSize: 6,427,212 bytesMD5: 16b80cae108c812a3e480a6b6b826162

1. Copy the extracted "bzImage" and "initrd.gz" to <ubcd>\ubcd\boot\cpustress\ directory.2. Make the bootable UBCD usb from this.3. When booting, select CPU -> CPUstress 2.1expl6, then press TAB to edit the boot options.4. In the command line, replace "linux.c32 /pmagic/bzImage" with "linux.c32 /ubcd/boot/cpustress/bzImage" and then press Enter to boot.5. Let me know if your keyboard works after that.

I copied those 2 files into the specified folder on my ubcd usb drive and followed your instructions during boot. Unfortunately my usb keyboard still didn't work. However, it did properly detect that the computer has 4 cpus instead of the 1 that is detected by the unmodified ubcd 5.2.1.

As I mentioned before, also PMagic's kernel had some issues with USB devices, even after the current latest stable release (2013_02_28). That's why I suggested trying (for CPUStress) PMagic's kernel of the latest testing version(s). The sources are also found in the same place.

@ady,Can you give me a link to a forum post or web page of the USB problem you're talking about ?I am not sure if your USB problem has something to do with my USB problem, here. My problem here is because of the missing drivers. PMagic kernel has made some important drivers (ehci-hcd, uhci-hcd, hid-generic, and others) into modules instead of built-in, so CPUstress cannot get those drivers unless I built them back in.

So this is what I've done with this custom kernel (in fixing the problem):

Make ehci-hcd, uhci-hcd, ohci-hcd built-in. (These are so important that Ubuntu, for example, has make them built-in, too.)

Allow module loading into kernel.

Include usbhid, hid-generic, hid-logitech, hid-microsoft and other kernel modules in CPUstress initrd, so it can support special keyboards.

Outside the kernel, the mdev program in initrd has been configured to 'modprobe' the drivers when needed. That's how I get this problem solved.

That problem is hard to test. I found another thread in the forum but it is not easy to test either.After googling I saw a post on fedoraforums that suggest it's a hardware problem. So I have nothing to do.

The links to those topics are older than the current PMagic. My previous comments regarding USB devices (including keyboard and mouse) having problems in PMagic, and changes made in PMagic, are for recent kernels (3.7+) and for recent PMagic versions (later than 2013_01_29).

Note, for example, that in the topic in PMagic's forum to which I linked before, there is a mention about not having USB problems when using "older" kernels (3.2.x, for example), while having issues with 3.7.x / 3.8.x kernels.

@all,I seriously suggest trying CPUStress with the latest TESTING version of PMagic and reporting feedback here (feedback, including what changes have been tried, like BIOS settings, USB port...).
